to think edelbrock intakes always fit is folly. of the seven i've had four required machine work; and i mean required! anything from wrong angles, being too wide, to the mounting flanges being tapered. i used to think this was only a mopar edelbrock problem but i've found these problems to be true on chevy's also. i take nothing for granted anymore. look at everything! when it comes to aftermarket parts i've become the eternal skeptic.
